Taller, Rangier, Heavier and Younger. Physically Gus could be the man to send Mousasi back to 185 where he belongs.

On Paper though as Good as Gustafssons striking is Mousasi's is a little better, he is MUCH harder to hit and lands as a considerabally higher percentage too (although Gus throws in much higher volume)

I think the Wrestling will be one way though, Id say Mousasi is at least as good offensivley wrestling but Gus's TDD is superb and Mousasi's is his biggest weakness. I could see Gus being the one to score TD's if the standup is close or not going his way.

Experience is the other thing because for men only a year apart Mousasi has seen more than twice as many bouts. I think this will be a close fight with Mousasi edging the Standup and Gus using a bit of wrestling to even the odds.

I could see a SD (and Gus is the home fighter) Im going to go for Gus via controversial SD here.

Think you sized it up about right Ben. Mousasi has the better striking, Gustaffson has the wrestling. Doubt either guy has it in them to finish the other, should be a relatively competitive fight. I'm interested to see what Mousasi does if he ends up on his back, you'd think finally being in the UFC might be adequate impetus for him to finally up his game off his back, or at least not be content to just lie on his back neutralising his opponent.
